Guardians are typically used in three situations: guardianship for an incapacitated senior (due to old age or infirmity), guardianship for a minor, and guardianship for developmentally disabled adults.
Other states with strong Castle Doctrine and stand-your-ground laws include: Alabama, Arizona, Georgia, Indiana, Kentucky, Louisiana, Montana, Nevada, Oklahoma, South Carolina, Tennessee, Utah, and Washington. Not all states give citizens as much leeway in protecting their personal property.
The castle doctrine is not a defined law that can be invoked, but a set of principles which may be incorporated in some form in the law of many jurisdictions. Justifiable homicide inside one's home is distinct, as a matter of law, from castle doctrine's no duty to retreat therefrom.
